I think you might have misunderstood me. I was talking about a crossover, or
more commonly known as an isolator.
There wouldn't be any mods to the dashboard. All an isolator does is isolates
the batteries, so they are not "bank"
charged. Just do a search on a battery isolator, and you will get many hits. It
connects to the alternator (+) and from there
goes to the batteries. Here is a link to the first of many hits. But I'm sure
you can find much cheaper sources

Also might look at the intergrator just below the isolator, its a different
option, that does something similar.
This was in response to your concern of one battery going dead, and dragging
the other with it.

changes over the years it could well do with a panel makeover"
